To know when to harvest there are many indicators, If soft-neck garlic you may notice that the leaves have all flopped over very much like onions. When you notice this you can harvest your garlic. If it is hard-necked garlic the first sign will be that the garlic scapes will appear, they start off curly but as the garlic becomes ready you will see them straighten up. This will coincide with the bottom leaves of the garlic starting to yellow. Again your garlic is ready to Harvest.
Giant Marrow preparation starts during the winter months. I prepare the soil in readiness for growing these Giants. These plants grow large and depending on how many you wish to grow will determine the size of the area required.
One way my partner and I have experimented with growing mushrooms is by inoculating hardwood logs. We buy dowels impregnated with the mushroom mycelium and just drill holes in the log and bang them in. The mycelium will then take between 8 months and a year to spread through the log and will give spring and autumn crops for up to 4 years! We are currently growing, Oyster, Shiitake, Lions mane and Chicken of the woods. It is very exciting.
